As detailed in this surprisingly safe for work promo, there is now a developer tool and ap store for "adult" aps (read "porn"). Until now, providers -- particularly Apple -- have expressly limited the availability of pornographic aps and content. Indeed, this is often cited as a reason to maintain control over apps and content by providers.
Google's Android operating system is an open system. Therefore, subject to your bandwidth cap, you can get adult aps and content for the first time.
It is usually asserted, but never proven, that adult content is a driver of technology adoption. It is often said that the VCR, cable, and the internet owe their initial success to the availability of adult content. Frankly, I think this is a crock. Adult content proved very popular once available, but there is no evidence that it drove adoption as is often claimed. the evidence is basically of the post hoc ergo propter hoc variety and people accept this because it confirms what we like to believe about human nature.
But cell phones have been fairly popular without the availability of porn, and Android has generated lots of buzz without the availability of porn. This will not prevent people from claiming a year from now that Android sales are driven by the availability of porn.
